AS 4276.9-1995 sets out a method, using membrane filtration, for enumerating faecal streptococci in water.

This Standard sets out a method, using membrane filtration, for enumerating faecal streptococci in water.NOTES:1 This method may not be suitable for strains of Streptococcus bovis and Streptococcus equinus that do not grow at 44C to 45C.2 Membrane filtration is suitable for enumerating microorganisms only when the turbidity of the water is low.3 Bacterial counts derived from membranes with fewer than 20 or more than 80 target colonies are approximate.4 A flow diagram of the procedure is shown in Appendix A.
